No, as documented, you need a matching native compiler to build a cross Ada compiler (e.g. build from the same 4.3 sources a native compiler first, and then use it to build the cross compiler). > 2) does it work to build 4.3 cross-gnattools with the current 4.3 Ada > compiler? It does in general. I do not know for avr in particular. > 3) Would a patch be accepted that makes the 4.3 gnattols be compilable > by 4.2 compiler? In general, no. On a case by case basis, assuming the patch is simple and does not make the code worse in terms of maintenance, then it can be OK. Arno
